Subject: [PATCH v1 1/2] arm: dts: k3-am69-aquila: Fix SPL USB DFU gadget failures
Date: Tue, 27 Jan 2026 11:14:11 +0100 [thread overview]
Message-ID: <20260127101413.2812815-2-ernestvanhoecke@gmail.com> (raw)
In-Reply-To: <20260127101413.2812815-1-ernestvanhoecke@gmail.com>
From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>
Around 1 in 20 times, the current R5 SPL fails to pull up the D+ line to
signal that a new USB device (the USB gadget used for downloading the
next stage) joined the bus.
With these strapping options, this is greatly reduced to 1 in thousands.

Fixes: 3f0528882c0d ("board: toradex: add aquila am69 support")
